l To all whom Lt nay cancer-7b.":

Be'it' knownjthat I," CH-IE R- FEnonsoN, a citizen ofthe United States, and aresident:

of Colton, in theoounty of- Whitman and ,full, clear, and exact description.

State of Washington, have invented a new and Improved.Grain Separating and VitriolizingMachine, ofwhich the following is a This invention relates to im rovements in machines for separating wi d oats from wheat, barley, or other grain, the main obj'ect being to provide a means for treating the grain with a cleaning solution to kill the smut germs, thus promoting the growth of the grain.

Other objects of the invention will appear in the general description.

cleaning, machine embodying my invention and then point out the novel features in the ingdrawi'ngs forming a. part of this specification, in which similar characters of referenceindicate corresponding parts in all the figures. 1

Figure 1' is a perspective view'of a machine embodying my invention; Fig. 2 s a side elevation thereof; Fig. 3 is a sectional elevat1on; F1g. 4 1s a detail in section showing a modification 1n the separating device; Flg.

.5gis a detail indicating the mechanism for operating the vertical conveyer employed; and. Fig. 6 is a sectional detail showing a portion of a screen shaking mechanism.

The main structure comprises. a fanning mill substantially of the ordinary construction; that is, it consists of a casing 1 in which is arranged a rotary fan 2 having on its shaft a pinion 3 meshing with a gear-wheel 4 oper-.

atvd by a crank in the upper portion of the casing is a hopper 6, the opening 7 in the lower portion thereof being regulated by a valve-plate 8. Below the hopper are ordinary screens 9 below which are reversely inclined deflecting boards 10, 11, the board 10 being designed to direct the grain onto the board 11, from' which the same passes underneath a head 12 onto a screen 13, which terminates at its outer end in a trough 14 and underneath the sort -n is a board 15 open at its lower end, it being understood that the said screen 13 and board 15 are inclined.

Arranged ,upon the screen 13 is a flexible material 16 suchforinst'ance, as canvas, the

I will describe-a grain separating and. arts 13 and 15,

- inner end thereof being secured to the board 11. -The screen 13 and the board 15 have lateral motion, andfor this urpose an cecentric 17'is attached to the fan shaft and is engaged by an' eccentric ring 17 from which a rod 18'passes to a-crank lever 19'having a rod 20 which;passes through an opening 21 to connection with a side member-of the board 15. Below'the' parts 13 and 15 is a downwardly and forwardly inclined. screen 22, to which'vibratory motion is im arted by means of an eccentric on the fan s aft, having a rod connection 23, with an arm 24 on a rock-shaft 25,from'whic'h an arm 26 extends upward and inward and has a rod connection 27 with 'said screen 22. 'It will be noted that a frame in which are the screens and the is' connected to swinging angers 2S. 7 The angle of the screen 22 may be adjusted ostsof the casing are provided. with e orations 29 for receiving pins 30' on w ich the screen frame may rest.- "Below the screen 22 are screening-boxes 31, which are here shown in the form of drawers. At the front of the casing and adapted to receive grain from the screen 22, is a horizontallydisposed liquid holding trough 32, in which-is a spiral conveyer 33, on the shaft of which is a sprocketwheel 34, engaged by a'sprocket chain 35, the said chain passing'over a sprocket-pinion 36 on the fan shaft.

Extending over the receptacle 32 is a perforated spray-pipe 37, having a pipe connection 38 with'a vessel 39, in which a cleaning liquid is to be placed ,[such for instance, asasolution of vitriol-water, formaldehyde or any other liquid solution that will kill the smut germ. The pipe 38 is provided with a valve 40, so that the supply of liquid may be cut off when desired or whenthe machine is to be used without the solution treatment.

communicating with a vertical tube'42 in which a spiral conveyer 43 operates;

The

shaft 44 of the conveyer43-passes through an opening in the upper closure of the tube 42, and is connected with a bevel whe'el 45, the said bevel-wheel meshing with a bevel pinion 46 mounted on a countershaft 47 to which is secured a sprocket-wheel 48 engaged by a chain 49, the said chain being operated from a sprocket inion 50 on-the' fan shaft.

having an opening normally closed by a slidcomprising a casing, ahopper in the up er ing gate 53, and attached to the-lower end of portion of the casing the box 52'are hooks 54 for supporting a bag into which the grain is discharged from said box.

.In operation, the-wheat or other grain which is generally mixed withwild oats, passes from the hopper 6 onto the screens 9 and through the same to the boards 10 and 11, and thence to the screen 13; the oats will be held in a flat position by means of the canvas 16, and will roll down the screen into the trough .14 and then out of said trough; the wheat'will ass through the openings of the screen 13 the board 15 and thence to the screen 22. ing through the screensand upon the boards,

the smut will be removed therefrom, and the grain will pass from the screen 22 into the 'receptacle 32 where 'it will be treated'with the' liquid flowing from the container 39, and in.

passing through the receptacle 32 the grain will bethoroughly soaked, as it is well understood that'thorough soaking can only take place after removing'the smut.

The spiral conveyor 33 moves the grain into the tube 42 and the liquid passing into said tube 42 will leak out through an opening in the lower end of said tube and into a an 56, so that by this arrangement there wil be practically no Waste of the liquid, as it may. e transferred from the pan 56 into'the re-- ceptacle 39 and used again. The grain discharged into the tube 42 will be' oarried. u ward by the conve er 43 and deposited in t 1e box 52 from'whicii it may be passed into a bag as before-mentioned.

I In, the modification shown in Fig.4, a step-like screen 57 is arranged over the'board 15, which terminates in a trough 58. In this construction the rain. and oats-pass onto the screen and in sliding over the steportions the oats will be vertically-ended an passed through the meshes of. the screen ontothe board 15 and then' out through the trough 58; the. wheat or similar grain ,bein too large to pass through the screen, wifi' fall upon the-screen 22.
